NCIt synonyms : Anti-CD19/CD28/zeta Modified CAR CD3 T Lymphocytes JCAR015;
NCIt definition : Genetically modified CD3-positive-enriched autologous T-lymphocytes transduced with
a replication incompetent gamma retroviral vector expressing a chimeric T-cell antigen
receptor (CAR) consisting of an anti-CD19 single chain variable fragment (scFv), fused
to the extracellular, transmembrane and intracellular signaling domains of the T-cell
co-stimulatory receptor CD28 and the cytoplasmic signaling domain of the zeta chain
of the TCR/CD3 complex (CD3-zeta) (CAR19-28z), with potential antineoplastic activities.
Upon intravenous administration, vadacabtagene leraleucel,is directed to CD19-expressing
tumor cells, and, upon binding to the T-cells, induce selective toxicity in CD19-expressing
tumor cells. CD19 antigen is a B-cell specific cell surface antigen expressed in all
B-cell lineage malignancies. The CD28 co-stimulatory molecule signaling domain enhances
activation and signaling after recognition of CD19. The inclusion of the CD28 signaling
domain may increase proliferation of T-cells and antitumor activity compared to the
inclusion of the CD3-zeta chain alone.;
